I received this morning my new 5 inch LCD for my Raspberry B+, I have got a PwnPI 3.0 version.

The LCD displays with a big black gap on the right side when connected for the first time. I figured it's because I haven't set the drivers...

Before downloading from Waveshare I tried editing the /boot/config.txt file, changing some parameters to see if anything changes to the display:

  • Tried adding "hdmi_cvt 800 480 60 6 0 0 0" : everything froze at boot, white screeen
  • Tried changing HDMI modes, groups: everything froze again and again and again...

So I decided to go with the installation procedure from the Waveshare wiki for the 5 Inch screen:

  • Downloaded LCD-show-150602.tar.gz from resources.

  • Extracted and untarred files.

  • Ran setup script: sudo ./LCD5-show
  • Rebooted

Got a white screen, with everything frozen

  • Took the SDcard out and edited config.txt again: at the end 9 lines were added after the LCD installation, I commented them all out with # to see if this is the problem

Now: the RPi boots, but won't start the GUI...

Any suggestions how can I install the screen correctly so I get use of all the screen's width? I don't care for the touch/pen use, I just need to stretch the display width!

  • Although waveshare may claim you can use their driver with a different image, unless they provide source code for it it is unlikely to be true. It will be more likely if you swap in the kernel and /lib/modules/x.x.x from their image, but that may lead to other problems. In short, caveat emptor.

    went to elinux.org/RPiconfig#Video_mode_options and found out the right settings, i needed to set hdmi_group=2 and hdmi_mode=14..that was all... so i guess it was worth the whole 15 euros..!!!.... in short, aut viam inveniam aut faciam

  • That was lucky. If you have time please leave an answer of your own if possible (there may be a rep bar on that).
